Description

Freezing buckwheat bean curd skin and production method thereof
Technical field
The invention belongs to frozen food manufacture field, relate to a kind of freezing buckwheat bean curd skin and production method thereof.
Background technology
Buckwheat is important cereal crops and resources of medicinal plant, is divided into sweet buckwheat and bitter buckwheat two kinds.According to estimates, the current world sweet buckwheat total output 500 ~ 6,000,000 t, Chinese total output about 750,000 t, after ranking Russia, occupy the 2nd, the world.And bitter buckwheat is by Chinese peculiar, total output about 300,000 t.Though buckwheat belongs to little ancestor crop in Grain in China crop, but nutritional labeling is unique, essential amino acid pattern can improve biological value with Major Cereal complementation, and the bioactive ingredients such as the flavones do not possessed containing other cereal and rutin, there is high medicine and health care value.Facts have proved: long-term edible buckwheat, can significantly improve body immunity, has outstanding effect to modern diseases such as control and assisting in treating hypertension, coronary heart disease, apoplexy.
In China's buckwheat producing region, always there is the tradition making buckwheat foods, and of all shapes and colors, local flavor is different.More representationally comprise noodle prepared from buckwheat, pancake, He Le, bowl stick together, fiber crops eat, skin of beancurd etc.Wherein, buckwheat bean curd skin is Jingzhou Prefecture's traditional-handwork special product, rises in Wang Jiaqiao town, Songzi City (the raw ramie region of rivers and lakes), deeply likes by the local common people.The raw material making buckwheat bean curd skin mainly contains buckwheat, rice, potato, mung bean.Traditional method is that buckwheat, rice boiling water are polished into starchiness after soaking, and add potato, green starch in proportion, after stirring, paste is spread out cutification in hot pot, be cut into silk after the cooling that takes the dish out of the pot, airing is air-dry.At present, have semi-automatic production line Some substitute traditional-handwork manufacture craft, but basic Making programme has no innovation.Generally speaking, in order to extend the shelf-life of skin of beancurd, still following traditional drying mode, namely adopting outdoor airing mode to carry out air-dry.Whole dry run needs constantly to carry out batch (-type) to material and stirs, and very easily causes skin of beancurd to break bar, fragmentation; Meanwhile, because drying time and degree restrict by weather conditions, if meet with overcast and rainy wet weather, skin of beancurd airing is insufficient, then likely cause product not resistant to cook, very easily stick with paste soup, even moldy metamorphism, have a strong impact on skin of beancurd edible quality.
Summary of the invention
The object of this invention is to provide a kind of freezing buckwheat bean curd skin and production method thereof.
